This invention relates to yarn holders or transfer combs employed to retain the-ends of a series of yarns wound upon a spool in the desired relation to each other;

Yarn holders of the type to which the pres: ent invention relates are extensively used in connection with the spools for tube frames, and serve to hold the ends of the different colored yarns wound upon a spool in place ash: the spool is taken from thespooling machine and transferred to the threading machine employed to draw the yarns through the tubes of atube frame.

In preparing tube frames for use upon.

1:; Axmmster looms a series of yarns'are Wound upon spools in accordance'with a'prearranged pattern. The spools are then presented to tube frames and the yarns are drawn through the individual tubes of the tube frames ready subsequent weaving operation. 1 c a It is essentialthat the yarns Wound upon a spool in accordance with a predetermined pattern have the cut ends held intheir proper relation to each other, so that in the'subse quent threading operation they'will be drawn through the tubes of the tube frames in the proper order. Y

It is therefore the common'practice to use a yarn holder or transfer comb to hold the yarnends side by side in their proper relation from the time aspoolleaves the spooling of thespool'with which it is to be used, and

* thecover is commonly formed of a .metal to be inserted in afabric as pile tufts in the YARN HOLDER strip U-shaped, cross section to'fit over the teeth of the comb; V

It is important'that the-cover or cap be locked in place upon a comb while'the comb I is associated with a spoolto hold the yarn ends in place, and several forms of spring .clipsliave' been proposed heretofore for removably fastening a cover to a, comb, but these fastening devices as constructed here.-

tofore have been more or less diflicult to 4 interengage and release. 5 They are also open to the obj ection'that they frequently become bent or broken while in use or instorage and necessitate a considerable expense for repairs. Thebreakage of these prior fastening devices has also been due largely to'the fact that they are provided with projecting portions that extend beyond the comb or the comb, the arrangement being such that y no portion of the locking means protrudes from the comb or cover and as a result they are well protected from injury. 1

A more specific feature of the invention' consists of locking means comprising coopcrating pins and notches, the construction being such that the parts are simple, strong and durable and are extremely easy to engage and disengage, and a further feature resides inspring means for preventing accidental movement of the parts in adirection to release a'pin fro m'its notch. a

Other features ofthe invention and novel arrangement of parts, in addition tothe above, will be hereinafter described in connection :with the accompanying drawings I which illustrate'one good-practical form of the invention. K

In preparing spools for use in tube frames the spools are commonly wound on spooling machines. These machines are provided with a creel or other means for supporting a large number of spools 10 provided with different colored yarns aadapted to be wound on a spool 11 in accordance with the pattern requirements of the row of tufts to be presented to the fabric by the spool. The spool 11 is conveniently driven during the winding operation by mounting it between the pair of lower rolls 12 and the upper floating roll 13, and the yarns as they are delivered to the spool 11 may be guided by the usual reed 14 having the upwardly extending pegs 15. The reed 14 is conveniently supported by the spaced'bracket's 16.

During the winding operation illustrated in Fig. 1 of the drawings, the comb 17 of the yarn holder is preferably supported below the series of yarns a in position to be moved into engagement with the: yarns, and the means shown to this end consists of a transversely extending bar 19, which is supported adjacent the opposite sides of the spooling machine by the racks 20 slidably supported in brackets 16. The teeth of these racks mesh with the teeth of the gears 21 secured to the transversely extending shaft 221 which may berotated by the crank handle 23. The upper edge of the transversely extending bar 19 may be provided with a groove adapted to receive the comb 17 and hold the teeth in. an upright position.

As soon as the desired amount of yarn has been wound upon the spool 11 the crank handle 23 may be rotated to elevate the racks 20 and combs 17 so asto introduce the teeth of. the comb between the adjacent yarns a, as shown in Fig. 2. The comb cover or cap 24 may then be placed over the teeth of the comb and secured to the comb by means to be described. The yarns a are then'cut'adjacent the yarn holder, whereupon this holder or transfer comb may be tried or otherwise secured to the wound spool 11, whereupon the spool may be placed in storage for future use or ma be conve ed direct to a threadin machine, not shown, but adapted to draw the yarns a through the individual tubes of a tube frame.

The winding machine above briefly described forms no essential part of the present invention but has been illustrated and described to make clear the field of use of the yarn holder or transfer comb embodying the features of the present invention.

The comb 17, as shown, may be formed of a flat metal strip having the lower edge portion folded upwardly, as at 25, to give stifl' nose to the metal strip and at each end of the comb are provided the end portions 26 and 27, which serve to protect the teeth of the comb. The cap 24, as illustrated, comprises a strip conveniently formed of metal U shaped in cross section to fit over the teeth 18 of the comb. The arrangement in the construction shown is such that the cap 24 does not. clamp the yarn a between the teeth of the comb, but prevents the yarn from escaping between the teeth by a lateral move-- ment, while the yarn may be drawn from be tween the teeth to facilitate the operation of drawing the yarn into the tubes of the tube frame.

The construction of the yarn holder or transfer comb so far described has been employed heretofore and constitutes one form of yarn holder with which the means of the present invention for removably locking the cover to the comb may be associated. It is to be understood, however, that the features of the present invention may be employed in connection with other types of yarn holders than herein illustrated and that the locking means of the present invention may be given various embodiments other than that shown.

In accordance with the particular embodiment of the invention illustrated, one protecting end portion of the comb 17, for eX- ample the left end portion 26 is provided with a relatively deep notch 28- adapted to receive a locking device 29, extending transversely between the spaced side walls of the cover 24. The opposite end portion 27 of the comb is shown as provided with a notch 30, of less depth than the notch 28, and the right hand end of the cover 24 is provided with a transversely extending locking device 31. After the locking device 29 has been placed within the notch 28, as above described, the locking device 31 is readily engaged with its notch 30 by moving the cover to the left to present the locking device 31 for engagement with the notch 30.

The locking devices 29 and 31 carriedby the cover, and as shown by Figs. 3 to 7 inclusive, are constituted as pins bridging the space between the side members of the cover above the lower edges of the side portions.

Inacc'ordance with the present invention means is provided to prevent accidental retrograde movement of the cover 24 once it has been assembled on'the comb with the lock ing devices engaged with their cooperating locking notches, with the important result that thespaced yarns'in the comb will be held means to this end a yielding member, such,

for instance as a spring 32, is caused to act upon the cover and urge it to its final locked position;

The spring 32 may be variously constructed and is conveniently mounted in the channel provided between the lower portion of the comb and the spaced up-turned portion 25, where it may be supported by a pivot pin 33 extending through a looped portion of the spring. The upwardly extending portion of the spring 32 preferably projects between and is protected by the side portions of the cover, and as shown is held in position to act against the pin 29 by the laterally extending tail portion 34, which may be retained in the position shown by a portion 35 of the comb turned inwardly over the end of the tail 34.

It will be seen from the foregoing that the means of the present invention for removably locking the cover to the comb areso constituted as to insure proper relation of parts for the purpose stated and present no protruding parts which extend beyond the comb or its cover, a condition which greatly reduces the likelihood of the interlocking parts being injured. It is further apparent that the parts 7 may be readily moved to and from their interlocked position by simply moving the cover 2 l'lengthwise of the comb 17. The engagement of the pins 29 and 31 with their respective notches 28 and 30 may be further facilitated by providing adjacent each notch the inclined portion 36 adapted to guide the pin downwardly into this notch.

While in the preferred embodiment of the invention shown and described-the pins 29,

31 and 33 have been illustrated as bridging the space between the walls of the cover or comb, it will be apparent that the desired re sult may be secured by forming these parts as an integral portion of the cover or comb by simply bending or distorting portions of the sheet metal inwardly in the modified construction of Fig. 8, wherein the locking device 37 is formed by forcing a small portion of each wall of the cover inwardly.

The means of the present invention for looking a cover to its comb are simple, strong and durable, and since all the parts are protected and do not project from either the comb or cover, the chances of these parts eing injured while the yarn holders arein use or in storage are practicallyeliminated.
